摘要：

The aim of this study was to assess the level of some phytochemicals in 19 raspberry cultivars grown in Lithuania. The content of total ellagic acid measured after 20 h acidic hydrolysis of investigated raspberry cultivars, varied from 119.8 (cv. 'Pokusa') to 323.5 mg/100 g (cv. 'Bristol'). The content of total phenolics ranged from 278.6 (cv. 'Pokusa') to 714.7 mg/100 g (cv. 'Bristol'). The total anthocyanins content varied from 2.1 (yellow cv. 'Beglianka') to 325.5 mg/100 g (black cv. 'Bristol'). The radical scavenging capacity of the tested raspberry cultivars highly correlating with their total phenolics and total ellagic acid content (r = 0.90 and 0.92, respectively). The results of this study expand the knowledge about variation in the content of valuable bioactive compounds in raspberries and may help for the selection and validation of the most productive cultivars.
